Feb. 18, 1941. G. c. PROSSER PORTABLE HOT-WATER RADIATOR Filed May 23, 1940 grwam bow G01 DE/V C. PHOSSER Patented Feb. 18, 1941 UNITED STATES PATENT I OFFICE 4 Claims.

This invention relates to portable hot-water radiators or heating units, and has for one of its objects the production of a simple and efficient unit which may be moved from place to place in a building to heat the area where heat may be desired.

A further object of this invention is the production of a simple and efficient portable radiator or heating unit wherein a removable gas or fuel tank is carried by the unit, so that the tank may be renewed or replaced when desired, thereby eliminating the necessity of permanent connection of the unit with 'a fixed source of fuel supply.

Other objects and advantages of the present invention will appear throughout the following specification and claims.

In the drawing:

Figure 1 is a side elevational view of the portable radiator;

Figure 2 is an end'elevational view thereof;

Figure 3 is a longitudinal sectional view taken on line 33 of Figure 2.

Figure 4 is a vertical sectional View taken on line 4-4 of Figure 3; 1 I

Figure 5 is a vertical sectional view taken on line 5-5 of Figure 3;

Figure 6 is an enlarged fragmentary sectional view taken on line 6-6 of Figure 2'.

By referring to the drawing, it will be seen that H] designates the frame which comprises a base II and a vertically extending portion 12 projecting at right angles to the base II at one end thereof. A series of radiator heating coilsv I3 is mounted upon the frame In in the manner shown in Figure 1.

The base II is provided with a fuel tankreceiving compartment 4 in which is mounted a removable fuel tank l5, which tank may rest upon the cradles l6. The base II is preferably supported upon a plurality of rubber-tired ballbearing casters C to facilitate the moving of the portable radiator heating unit from place to place, whereby the desired area within a building may be conveniently heated by moving the radiator to the desired position. The tank I5 is provided with an upwardly extending burner I! at one end and a suitable valve I8 is provided to control the passage of fuel from the tank l5 to the burner I1. A door I9 is hingedly secured at one end of the compartment l4 near the burner I! to facilitate lighting, and side doors 20 may be provided adjacent the compartment I 4 to facilitate the placing of the tank l5 in position, or the removal thereof from the portable radiator when desired. Suitable windows 2| and 22 are placed in the doors l9 and 20 respectively.

The vertically extending portion l2 of the frame l0 carries a water heating tank 23 in suspended relation above the burner H, the tank 23 having a concave lower face 24 just above the burner I! to cause the flame from the burner H to spread outwardly and thereby take advantage of a maximum heating capacity. The tank 23 is connected to the upper end of the series of radiators l3 by means of an upwardly extending pipe 25 and is connected to the lower end of the series of radiators l3 by means of a pipe connection 26, as shown in Figure 3.

A reservoir tank 21 is carried within the vertically extending portion I2 upon one side of the pipe 25 and communicates with the water heating tank 23 by means of a pipe 28 whereby water may be admitted or supplied to the tank, 23 by opening a suitable valve 29. A drain-off cook 30 is carriedby the lower end of the tank 21, and the tank 21 is also provided with a filling opening 3| at the top thereof which is closed by a suitable cap.

A blow-off tank 32 is carried within the vertically extending portion l2 to one side of the pipe 25 and opposite the tank 21, and this blowoff tank 32 is connected to the upper end of the series of radiator coils I 3 by a blow-off cook 33 mounted within the tank 32 so as to provide a pressure relief for the radiator coils l3 should excess pressure become accumulated in the radiator coils l3. The outer radiator coil I3 is provided with an air cook 34 of the conventional type. The tank 32 is provided with a drain-off cock 35 at the bottom thereof.

From the foregoing description, it will be seen that a very simple and eflicient portable radiator or heating unit has been provided whereby a removable fuel supply tank such as a Philgas tank or other fuel reservoir may be renewed from time to time thereby avoiding the necessity of permanently attaching the burner 11 to a fixed fuel supply line. Consequently, the radiator or heating unit may be conveniently rolled from place to place through the medium of the casters C and thereby enable the heating unit to supply heat to a desired area, and the heating unit may be changed from. place to place as desired.

An important feature of the present invention is the assembly and design of the device whereby a maximum heating capacity is provided within a minimum space and whereby a sufiicient supply of water is maintained in the reservoir 21 and means is also provided to take care of an oversupply of pressure within the radiator. Furthermore, by extending the pipe upwardly between the pipes 21 and 32 this pipe will be braced and the heating tank 23 because of its connection will be firmly supported within the upwardly extending portion l2. Furthermore, a minimum amount of water is carried within the tank 23 thereby providing a complete and proper circulation and avoiding the necessity of subjecting the heating element to a large area to be heated by the burner.

It should be understood that certain detail changes may be employed in the construction of the present device, without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claims.

Having described the invention, what I claim as new is:
